Explicație pas cu pas:
1/2 + 3/2 = 4/2 = 2
5/6 - 4/6 = 1/6
5/8 + 3/8 = 8/8 = 1
4/3 - 2/3 = 2/3
1/5*5/6 = 1/6
7/3*9/14 = 3/2
5/8*(-8/10) = -1/2
2/6 - 3/2 = 2/6 - 9/6 = -7/6
5/4 + 1/2 = 5/4 + 2/4 = 7/4
7/6 + 2/12 = 7/6 + 1/6 = 8/6 = 4/3
-3/8 + 4/3 = -9/24 + 32/24 = 23/24
1/6 *3 + 2 = 1/2 + 2 = 1/2 + 4/2 = 5/2
